  • Design of an advanced intelligent instrument with waveform recognition based on the ITMS platform

    Searching for similar behaviours in previous data plays a key role in fusion research, but it can be quite challenging to implement from a practical point of view. This paper describes the design of an intelligent measurement instrument that uses Similar Waveform Recognition Systems (SWRS) to extract knowledge from the signals it acquires. The system is perceived as an ethernet measurement ...

  • Data Logger vs DAQ

    Key Differences Between Data Logging and Data Acquisition What is the difference between a Data Logger vs DAQ System? A data logger is a type of data acquisition system, but a data acquisition system is not necessarily a datalogger. There are several key functional differences in how the market understands these two classes of instruments. While the differences between these ...

  • Locating subverted processes using random packet comparison in SCADA systems

    A supervisory control and data acquisition (SCADA) system may be subject to integrity attacks. Anomalies in sensor measurements may be used to detect these attacks, but such techniques do not permit us to locate attacking nodes. We propose a novel technique to enable this. Each participating network node probabilistically copies packets and marks them with routing information, before encrypting ...

  • Servo-Controlled Cuboidal Shear Device

    A servo-controlled cuboidal shear device with automatic data acquisition system is described. Provisions are made for pore-pressure measurements with specially designed “needle” piezometers. Complete stress-strain curves can be obtained with strains up to 20%. The application of servo-control in Ko consolidation and strain controlled loading is illustrated with flow charts and experimental ...

  • Aircraft wing payload modification - Case Study

    RMC Engineering, Turkey An aircraft operating company in Turkey wanted to modify the wing payloads without drastically affecting the flight envelope. Any aircraft is designed for a specific flight speed which is limited by wing flutter. Thus, anything that affects the natural frequencies of the wing has the potential to reduce the flight speed and narrow the flight ...

  • Method for irrigation scheduling based on soil moisture data acquisition

    The water requirements of crops are dependent on evapotranspiration (ET), soil chemistry, and the crop’s maximum allowable depletion (MAD). Direct measurements of root zone soil moisture, water application along with published ET values and soil textures, can be used in a soil water balance model that can significantly optimize irrigation efficiency. Over the past five years, advancements in ...

  • EPA Method 8270D Analysis Using Narrow-bore GC Columns and Fast Data Acquisition with a Quadrupole GCMS System - Case Study

    Analytical support of environmental programs has been conducted for several decades using standard-bore capillary columns (0.25mmid) and quadrupole GCMS systems. Depending on method conditions and program requirements, the QC measures can consume a significant portion of a 12-hour shift, leaving less time for analysis of real-world samples. Typical cycle times (time from beginning of a run to the ...

  • Improved real-time data anomaly detection using context classification

    The number of automated measuring and reporting systems used in water distribution and sewer systems is dramatically increasing and, as a consequence, so is the volume of data acquired. Since real-time data is likely to contain a certain amount of anomalous values and data acquisition equipment is not perfect, it is essential to equip the SCADA (Supervisory Control and Data Acquisition) system ...
